Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0026] Combine Figure 1 The utility model is a bolt assembly with an anti-loosening function, including a bolt component 1, a fixing nut 2 is rotatably provided on one side of the bolt component 1, and an anti-loosening limit nut 3 is inserted on one side of the fixing nut 2. The bolt component 1 includes a threaded rod 11, one end of the threaded rod 11 is set as a threaded opening 113, and an oblique slot 112 is opened on the threaded opening 113, and the oblique slots 112 are arranged in a circular array. There are four groups of them, and the fixing nut 2 is threadedly sleeved with the threaded opening 113. The anti-loosening limit nut 3 includes four groups of anti-loosening clamps 32 inserted into the oblique slots 112, and one end of the anti-loosening clamp 32 is movably engaged with the limiting sleeve 31.

[0027] Specifically, the threaded rod 11 and the fixing nut 2 are threadedly connected through the threaded opening 113. After the fixing nut 2 is tightly connected to the threaded rod 11, the anti-loosening clamp 32 is inserted into the oblique slot 112, and at the same time, the four sets of anti-loosening clamps 32 are kept in a sliding and engaging state in the limit sleeve 31, and then the limit sleeve 31 is tightened along the threaded opening 113, so that one end of the fixing nut 2 can be buckled to prevent the fixing nut 2 from loosening. At the same time, the setting of the anti-loosening clamp 32 being inserted into the oblique slot 112 increases the friction between the fixing nut 2 and the anti-loosening limit nut 3, which can further prevent the fixing nut 2 from loosening. This structure is simple to operate, can eliminate bolt loosening, and is conducive to popularization and use.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] Example 1:

[0030] Combine Figure 2-Figure 4 The bolt member 1 further includes a nut 12 fixedly arranged on one side of the threaded rod 11. A rotation groove 121 is provided on the nut 12. The nut 12 and the threaded rod 11 are fixed to each other. A screwdriver can be inserted into the rotation groove 121 to tighten the screw.

[0031] A sleeve groove 111 is provided on the threaded rod 11, and the bolt member 1 also includes a rubber member 13 arranged in the sleeve groove 111. The diameter of the sleeve groove 111 is smaller than the diameter of the threaded opening 113, so that the rubber member 13 is sleeved in the sleeve groove 111 and is not easy to separate. The rubber member 13 enhances the friction between the nut 12 and the workpiece.

[0032] A rubber slot 122 is formed at the upper end of the nut 12 , and a rubber block 131 is provided at the upper end of the rubber member 13 corresponding to the rubber slot 122 . The rubber slot 122 and the rubber block 131 fit together to achieve positioning and fixing of the rubber member 13 .

[0033] The fixing nut 2 includes a hexagonal nut 21 that is sleeved on the outside of the threaded rod 11. A nut built-in thread 22 that fits with the threaded opening 113 is provided inside the hexagonal nut 21. The hexagonal nut 21 is threadedly fixed to the threaded opening 113 through the nut built-in thread 22. The opening of the oblique slot 112 does not affect the rotation of the nut built-in thread 22.

[0034] Example 2:

[0035] Combine Figure 5 and Figure 6 The inner side of the limiting sleeve 31 is provided with a limiting thread 311 that matches the threaded opening 113, and the other end is provided with a limiting slot 312 that engages with the anti-loosening clamp 32. The opening of the limiting thread 311 allows the limiting sleeve 31 to squeeze the fixing nut 2 forward, so that one end of the fixing nut 2 is buckled, and the limiting slot 312 and the anti-loosening clamp 32 are engaged with each other to limit the anti-loosening clamp 32.

[0036] The anti-loosening clamp 32 includes a rubber oblique insertion rod 321 inserted into the oblique slot 112. The outer side of the rubber oblique insertion rod 321 is set to soft silicone and the inner side is metal. The metal material enables the anti-loosening clamp 32 to be directly inserted into the oblique slot 112. The setting of the outer soft silicone can support the fixing nut 2, increase the friction between the fixing nut 2 and the limit sleeve 31, and prevent loosening.

[0037] The anti-loosening clamp 32 also includes a thickening block 322 fixedly set at one end of the rubber oblique insertion rod 321, and a locking block 323 is set on the outside of the thickening block 322. The outer diameter of the thickening block 322 is the same width as the threaded opening 113, and the outer diameter of the locking block 323 is the same width as the inner wall diameter of the limiting slot 312. The connection between the thickening block 322 and the locking block 323 enables the limiting slot 312 to engage the locking block 323 and squeeze forward to complete further fixation.
